One way to remember for any V configuration engine, the side with the most forward cylinder is Bank 1. That most forward cylinder is also number 1 cyl.

Thank you all for your help.
Replaced O2 but still get code

You never told us the code.?
Check the harness and chassis harness plug. Sometimes the pins get pushed out or the wire breaks inside the wire insulation. You may have to Ohm out the circuit to the PCM to make sure there is not a break. If it is an O2 sensor Heater malfunction code it could also not be recieving power.
But can't really say since you didn't post the code(s).
